About these 3rd Grade 3-Digit Addition and Subtraction worksheets and activities
In Grade 3, students build on their understanding of place value to fluently add and subtract three-digit numbers. Our worksheets and activities cover both 3-digit plus/minus 3-digit and 3-digit plus/minus 2-digit problems, helping students develop regrouping and borrowing skills. The resources also reinforce related concepts like estimation, word problems, and mental math strategies.
Each resource is designed to be scaffolded, offering varied levels of difficulty to support differentiation. Students practice with printable and digital formats, making it easy to use in centers, as independent practice, or for homework. The activities are no-prep and classroom-ready, saving teachers valuable planning time.
Using these in your classroom
Teachers can use these resources flexibly across instructional settings. Introduce concepts during whole-group lessons, then assign the worksheets for small-group work or math centers. The differentiated options allow struggling students to focus on basic regrouping while advanced learners tackle mixed problems or multi-step word problems. Use the digital versions for interactive whiteboard practice or assign them for homework. These resources also work well for intervention, review before assessments, or as quick checks for understanding. The print-and-go format makes them ideal for substitute plans or extra practice.
